The invention relates to a so-called savings calendar, i. e. an apparatus which shows the day of the week, the date and the name of the month or,.maybe, vonly two of these indications, and which is adjusted from ,day to day by the insertion of one or morecoins. i

The various calendar indications, such as the name of the day of the week, the date and the name of the month, are arranged along thev periphery of discs disposed alongside of one another on a common shaft. The latter is journaled in two side walls interconnected by means of;

' tus, without the use of any handle or the like.

Thereby the operation of the apparatus is simplied, and `any errors due tol forgetting to move Fig. 1 shows the apparatus in front elevation, the front wall of the enclosing casing being removed,

Fig. 13 shows a modified construction.

As shown in Fig. 1, the-apparatus is enclosedl in a casing |2, the front wall I3 of which, Fig. 2,` is removed. The apparatus has two side walls I4and I5, which are heldtogether by means of bolts I6, II and I8. In the side walls a shaft I9 is journaled, on vwhich three equallyA large cylindrical discs are loosely mounted, viz..the disc 20, on the periphery of which the names of the days of the lweek are inscribed, the disc 2| the periphery of which carries the date numbers and the disc 22, the periphery o-fY which carriesJthe names of the months. In the front wall I3 of the enclosing casing', Fig. 2, a rectangular opening 23 is provided, and inside'of the latter there is attached to the side wallsv I4 and I5 an'opaque shield 24 with three windows 25, which are shown with dotted lines in Fig. 1, the shield 24 itself being omitted in this ligure. As shown in Fig. 1, the indication: THURSZZ SEPT correspondingto the momentaryY position of the discs to 22 can be-read through these window openings. f

In the side walls I4 and I5, asshown in Fig. 2, a rotary shaft 26 is journaled, which onthe outside of the side wall I4 supports, loosely mounted on the shaft, a double arm 21, 28, one branch 28 of which is ending in a hook 29. r In the rear wa11'30 of the enclosing casing, Fig. 2, a vertical coin-insertion slot 3| isprovided, vand inside of the latter, in a slit 32 in the side wall I4, afpin 33 is xed, which all depending on the size oil the coins can be'adjusted up or down.`V The sideV wall I4 supports further a coin chute 34 open at the top and at the bottom. The end of the force-the arm 2'I upward.,A When the coin has passed between the pin 33 andthe arm'2I, it will drop down through the coin chute 34 to a 'i collecting receptacle disposed below the appara-A tus'. butv notv shown `on the drawings.

To, the. wallv I4 a. pin .36 is attached, about which an arm 31 can rotate. This arm is fitted with a hook 38 and an extension, which projects into the coin chute 34, where it is actuated by the coin dropping through the coin chute. The arm 31 is actuated by a spring 40.

This part of the apparatus acts in the following manner.

When the coin 35 is pressed through the coin slot 3 I, it will lift the arm 21, whereby the hook 29 cornes into engagement with the hook 38, so that the arm 21, 28 remains locked in this position. By the subsequent drop through the coin chute 34 the coin actuates the arm 31 in such a manner that the hook 38 releases the hook 29, anda spring mentioned in the following will then return the arm 28 into the position shown in Fig. 2. The motion of the arm 21, 28 caused hereby effects the adjustment of the calendar discs 20, 2|, 22, as described in the following.

As mentioned above, the arm 21, 28 is loosely mounted on the shaft 26. By means of a pin 4I, a pawl 42 is pivoted to the 4arm 28, which pawl is in engagement with an eight-toothed ratchet wheel 43 on a shaft 44. On a pin 45 a check pawl 46 is pivoted, which similarly is in engagement with the ratchet wheel 43. A spring 41 connects the pawl 42 with the check pawl 48, and holds the two normally in engagement with the ratchet wheel 43.

When as shown in Fig. 2 a coin 35 is inserted, the latter will turn the arm 21, 28 in such a manner that the pawl 42 will move the ratchet wheel 43 one tooth forward in a counter clockwise direction, after which the check pawl 46 jumps into the next tooth space in the ratchet wheel and at the same time, as mentioned above, the hook 29 comes into engagement with the hook 38, and becomes locked by the latter as shown in Fig. 3. When now the coin drops through the coin chute, it will actuate the arm 31 in such a manner that the ratchet wheel 43 is thereby rotated one tooth, i. e. one eighth of a revolution forward. 'I'his happens regularly whenever .a coin is inserted.

To the shaft 26 there is attached, Fig. 4, behind the side Wall I4 of the apparatus, an arm 48 with a bent wing 49, which projects through an opening 50 in the wall I4, and is taken along by the arm 28, when the latter is rotating, when a coin as mentioned above is inserted into the apparatus. The arm 48 is further fitted with a tooth 5I, which co-operates with a wheel 52 with four teeth 53. This wheel, which is shown in perspective view in Fig. 5, is mounted on the shaft 44, but behind the wall I4 and in the same plane as the arm 48, which is actuated by a spring 54.

The position of the wheel 52 shown by full lines in Fig. 4 corresponds to the position of the other parts in Fig. 2. By the insertion of a coin the arm 28 moves, by means of a pressure against the Wing 49, the arm 48 towards the position 48 shown by dot-and-dashed lines in Fig. 4, and at the same time the wheel 52 is rotated in such a manner that a tooth 53 will come opposite the end of the tooth 5I in the position 5I of the same in such a manner that the arm 48 will be locked in the position 48', while the other members return into their normal positions, Fig. 2. When now another coin is inserted, the arm 21, 28 is again moved as described, but this time it does not take the arm 48 along. On the other hand it turns the wheel 52 one eighth of a revolution forward, so that no tooth 53 will now stop the tooth 5I for which reason the arm 48 now, while actuated by the spring 54, can follow the return motion of the arm 21, 28 into the position shown. in Fig. 2.

The arm 21, 28 has consequently to be moved twice up and down, in order that the shaft 26 with the arm 48 may be moved once back and forth, and this means that the insertion of two coins will be required for adjusting the calendar.

By means of a hook 55, Fig. 2, adapted to turn about the shaft 26, the pawl 42 can now be locked in the position 42 shown with dot-and-dashed lines, so that it cannot any longer actuate the ratchet Wheel 43, and the calendar members can then be adjusted merely by the insertion of one single coin, the ratchet wheel 43 and the wheel 52 being thereby set entirely out of function, and the arm 48 being now able to follow the motions of the arm 21,28.

In order to make sure that also small coins, by dropping through the coin chute 34, will actuate the arm 31, one side wall 55 of the coin chute is pivoted about a pin 51, in such a manner that it can be adjusted to fit the size of the coin.

A ratchet wheel 58, Figs. 1 and 6, with twentyeight teeth is connected with the day disc 20. On the shaft 26 an arm 59 is attached, which at the bottom is connected to a pawl 6I by means of a hinge pin 68. The said pawl is tted with an aperture 62 encircling a shaft 63 journaled in the side walls of the apparatus, and is maintained lifted into contact with the shaft 63 by means of a spring 64. The pawl 6I is fitted with a driving tooth 65 and a stopping tooth 66. When the shaft 26 by the insertion of a coin, as described above, has been turned in the direction of the arrow 61 shown in Fig. 6, the driving tooth 85 will come into engagement with the ratchet wheel 53 and rotate the same and the disc 28 one tooth forward, and by placing itself under the following tooth of the ratchet wheel 58 the stopping tooth 66 will prevent the said wheel from being flung more than one tooth forward.

In this manner the day disc 28 is adjusted one step forward, whenever the shaft 28 is turned in the direction of the arrow 61, Fig. 6.

As shown in Figs. 1 and '1, a ratchet wheel 6B with thirty-one teeth is provided in connection with the date wheel 2|. On the hinge pin 68 of the arm 59 there is suspended still another pawl 69 with an opening 10 enclosing the shaft 63, and

also this pawl is maintained lifted up against the I shaft 63 by means of a spring 1I. The pawl 69 supports a driving tooth 12 and a stopping tooth 13, which when the shaft 26 is turned in the clock-wise direction moves the ratchet wheel 58 one tooth forward, in the same manner as the l pawl 6I, with the teeth 65 4and 66, rotated the ratchet wheel 58 one tooth forward. In this manner the adjustment of the date disc 2| is effected normally from day to day, but at the change of month, when the month passed has less than thirty-one days, and the date wheel consequently has to be moved more than one step forward, another mechanism enters into operation.

In rm connection with the month disc 22, Figs. 1 and 10 to 12, a disc 14 is provided, the periphery of which is divided into I2 parts, and is fitted with incisions the depth of which corresponds to the number of days of the various months, in such a manner that no incisions are provided for the months with thirty-one days,

While on the parts corresponding to months with thirty days there are incisions 15, and on the part corresponding to the month of February there is an especially deep incision 16. To the shaft 26 a hook-shaped arm 11 is attached, which owing to Cal the action of the spring 54, Fig. 4, rests against to the hook-shaped arm 11, as shown in Fig. 10,v

resting against a portion of the disc Y14 that corresponds to a month withlthirty-one days, and

'the rotationof the shaft 26 in consequence of the insertion of a coinis in this case just large enough, as described above, to turn the ratchet wheels 58 and 68 one tooth forward by means of the pawls 6| and *59.V In the months during whichV the hook-shaped arm 11 vrests against the bottom of one of the incisions 15, the rotation of the shaft 26 by the insertion of a coin is somewhat greater, and in the month of February, during which the arm 11 rests against the bottom of the incision 16, still somewhat greater. Fig. 8 shows the position normally occupiedv by the arm 59 lwith the pawl 69 during themonth of February, when the latter has twenty-eight days. The pawl 69 is here moved so far to the right that the shaft 63 will here be situated at one end of the incision VAs shown in Figs. 1 and 8, the side of the ratchet wheel 68 is fitted with a pin 18, which co-operates with an auxiliary pawl suspended from a pin 19 on the pawl 69. This auxiliary pawl has one single, obliquely cut tooth 8|, and is actuated by a spring82, which lifts it up against a pin 83 fixed r on the pawl 69. When the pin 18, by the rotation of the ratchet wheel 68, moves past the tooth 8|, it will press the auxiliary pawl 80 downward, but when the pin has passed the tooth 8|, .the spring 82 will again lift the auxiliary pawl 80 up into contact with the pin 83.

The mechanism is now adjusted in such a manner that the pin 18 will pass the tooth 8| just on the last day of the. month, and the next time when a coin is inserted into the apparatus, and the shaft 26 in consequence thereof is rotated, the tooth 8| will move the ratchet wheel 68 so many teeth forward, by means of the tooth 18, that the date disc 2| connected to the ratchet wheel will show the date In leap years, in which February does not have twenty-eight but twenty-nine days, the hookshaped arm 11 must not rest against the bottom of the incision 16, but has to be maintained lifted some distance above the same. This is attained, as shown in Figs. 10 to 12, by suspending on a pin 84, on the wall I5, a lever 85 with a hook 66. The arm 85 rests normally against a stop 81 attached to the wall l5, and is in this position inoperative. In the wall l5 a rotary pin 88 is journaled, which supports a four-toothed star wheel 89 with a pin 90, which when the star wheel occupies the position shown in Fig. 12 lifts the arm 85 so far that the hook-shaped arm 11 will rest against the hook 86, and by the latter will be prevented from reaching the bottom of the incision 16 in the disc 14. On the latter a pin 9| is attached, which for each revolution of the disc, i. e. every year, adjusts the star wheel 89 one tooth forward. A spring 92, which rests along the star wheel, holds the same in position during the intervals between the rotations of the said wheel one quarter of a turn forward by means of the pin 9|.

Outside of the wall I5 a disc 93 is attached on the pin 88, by means of which disc the star wheel 89 can be adjusted in such a manner that the pin 90, when the year is a leap year, will occupy the position shown in Fig. 12', where. it lifts the arm 85, and when the star. wheel once has been adjusted correctly, the pin 9| will adjust the same automatically from year to year. Only the skipping of the leap year every hundred years cannot be effected automatically by the apparatus in the construction described. f

Whenever the date wheel 2| has been givenv one revolution, the month disc 22 has to be adjusted one twelfth of a revolution forward. This is effected by the mechanism shown in Fig. 9. To the side of the` date wheel 2|, a spiral-shaped disc 94 vis attached, which is fitted with one tooth 95 ctx-operating with a nose 96 on an arm 91, which isv attached to the shaft 63.- About a pin 98 on the arm 91 a pawl 99 is pivoted, which rests against the periphery'of a gear wheel |00 with twelve teeth, which is rigidly connected to theV `month disc 22.' A tension. spring |0| connects the pawl 99 to the bolt I6. On the side of the arm 91 a stop |02 is provided. When the tooth moves past the nose 96, and the arm 91 while actuated by the spring |0| is moved in the direction of the'arrow |03, the same spring will cause the pawl 99 to engage the gear wheel |00, whereby the latter and, thereby, the month disc 22 will be turned one twelfth of a revolution forward. At the same time the rotation of the arm 91 will move the stop |02 into a toothspace in the gear wheel |00, and stop the same, so that it cannot be flung too far forward.

As shown in Figs. l and 9, a attached to the bolt I6, which spring maintains the gear wheel |00 in its position of repose, and further as shown in Figs. 1,'6 and '1 a plate spring |05, the bifurcated body of which serves to hold f the ratchet wheels 58 and 68 in position.

The invention may be used in other constructionsthan the one shown on the drawings, and the details described may be replaced by other ones having the same or a similar effect. The mechanism may further be supplemented by a member which shows the year, and is readjusted automatically from year to year.

A modified construction illustrated in Fig. 13 shows that the arm 21, 28 may be fixed on the shaft 26, in which case the parts 4| to 54 may be omitted, and the apparatus acts then every time a coin is inserted into the mechanism. In that case the arm 21, 28 receives, by the insertion of a coin, a motion the magnitude of which varies 'r greatest in the shortest months.
